Flow Through Helical Coil
Product Code : LSK-TWL-10815
Flow Through Helical Coil (SKU LSK-TWL-10815) is a closed-loop water rig for studying flow through a 15-turn stainless steel coil, with a rotameter for flow rate and two manometers for pressure readings. It is used in fluid mechanics and chemical engineering laboratories at degree and diploma level. Science Lab Supplies manufactures the rig at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it direct to institutions, tender contractors and distributors.
Specifications
Every technical detail of the rig is listed in the table below. In short, stainless steel tube of about 21 mm OD is wound in 15 turns to a 12-inch coil, and a fractional horsepower pump circulates water from a 50-litre sump through GI and PVC piping on a painted structure with a control panel.

Applications and Experiments for the Flow Through Helical Coil
Students set a flow rate on the rotameter and read the two manometers to see how pressure changes as water passes through the coil. Repeating this over a range of flows shows how a curved, coiled path affects flow compared with a straight pipe, a standard topic in fluid mechanics lab experiments.
- B.Tech/B.E. chemical engineering: fluid flow operations laboratory.
- Mechanical and civil engineering fluid mechanics labs: pressure drop in coiled tubes, set against series and parallel straight pipes on the Pipe Network Apparatus.
- Polytechnic diploma practicals: using a rotameter and manometers on a flow rig, then comparing venturi, orifice and variable area meters on the Flow Meter Demonstration.
Standard Scope of Supply
The rig is supplied as one unit on its painted structure, with the 15-turn stainless steel coil, FHP circulation pump, 50-litre sump tank, rotameter, two manometers, GI and PVC piping and the control panel with on/off switch and mains indicator. Water and electricity are connected on site.
Packing, MOQ and Lead Time
You may request a price for a single rig or for a full fluid mechanics lab. The quotation sets out packing, delivery time and price for that quantity, and other flow benches from the Training Workshop Labs range can be added to it.

Frequently Asked Questions
What is the coil made of and how big is it?
The coil is stainless steel tube, about 21 mm OD and 17 mm ID, wound in 15 turns to a coil diameter of 12 inches (about 305 mm).
How are flow and pressure measured?
Flow rate is read on a rotameter and pressure on two manometers. Water is recirculated from a 50-litre sump by an FHP pump, so no continuous water supply is needed during the test.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The rig is fabricated at its own factory in Saha, Ambala, India, and quotations are sent directly from the factory.
Can it be combined with other items in one order?
Yes. Several flow benches, such as the pipe friction and Reynolds rigs listed below, can go on one quotation; send your list, quantities and delivery location through the contact page for an item-wise price.
